中文摘要：

通过在转盘轴承内部植入各种传感器，由NI数据采集卡采集数据并采用无线传输通信，实现转盘轴承的在线监测。该测试系统可在60m的距离实现低速及高速信号采集，以及多个无线网的组网，利用PC机实现数据采集、保存及后处理分析，可有效地提取早期故障信号以及进行智能注油和报警控制。

英文摘要：

Using the NI digital data acquisition card and wireless transmission communication, realize the online moni-toring of slewing bearings which integrated various types of sensors in the bearings. The test system is able to achieve high speed and low speed signal acquisition within a distance of 60m, and the system allows a plurality of wireless net-work. The PC is used to realize data acquisition, storage, processing, analysis and effective extraction of early fault sig- nals and intelligent oiling and alarm control.
